Frequently asked questions

Why convert to WebP?+

WebP gives smaller files than JPEG or PNG at the same visual quality — typically 25–35% less — so pages load faster. Every modern browser supports it.

Does quality affect PNG?+

No. PNG is lossless, so the quality slider only applies to WebP and JPEG. For PNG the tool re-encodes without a quality setting.

Will it make my image larger?+

Sometimes — re-encoding an already-optimised or tiny image can add a few bytes. The tool shows the size change so you can tell, and you can lower the quality or keep the original.

Is my image uploaded?+

No. The conversion runs on a canvas in your browser with your own file; it never leaves your device.
